It appears that NVIDIA has removed GPU PhysX support for all 32-bit games in its latest RTX 50 series GPUs.

RTX 50 series users can now gain access to GPU-accelerated PhysX effects in supported titles.
wait? i thought it was a hardware thing, so you're telling me it was there all the time and they just... turned it off?
That’s an excellent update. I thought this had something to do with the hardware itself and not just a software patch but either way this is great news
Great news! Initially was disappointed that my Steam copy of AC4: Black Flag wasn't compatible on my new 5070 ti laptop but since the update, happy to say I have downloaded and played the game successfully (Black Flag's my favorite AC).

This article shows the X58 and EVGA RTX 3080 'Black' Gaming GPU performance. The article consists of 23 benchmarks across several games and synthetic benchmarks with multiple resolutions. The article also contains power consumption, more in-depth information and comparisons for the X58 vs modern platforms.

The Nvidia PhysX SDK has just gone open source, meaning that developers can just simply download their SDK and tweak and extend it.
Really hope this brings new advancements to Physix. The last big advance in the tech was Half-Life 2.
That’s really lame.
